A major use of refrigeration is in the preservation, storage and distribution of perishable foods. Cold room is refrigerated space where low temperatures maintain for preservation of Food. The demand of cold room is going to increases due to adverse climatic conditions over worldwide so it needs to develop a cold chain which includes harvest cooling (pre-cooling) cold room transport to market. This design of cold storage is adaptive design which is operated on evaporative cooling suitable for preservation of the vegetables and fruit. The cold room is designed with refrigeration capacity 1.15 TR. During design these system various design parameter like cooling load calculation, selection of compressor, thermostatic expansion valve, condenser capacity and piping design are considered.
Keywords: Evaporative cooling, Cooling load calculation, Latent heat and sensible heat.
